Google has released Chrome version 141.0.7390.65\/.66 for Windows and Mac, along with 141.0.7390.65 for Linux, addressing multiple critical security vulnerabilities that could allow attackers to execute arbitrary code<\/a> on affected systems.\u00a0<\/p>\n

The update, announced on October 7, 2025, includes three significant security fixes that pose serious risks to users worldwide.<\/p>\n

Heap Buffer Overflow and Memory Corruption Flaws<\/strong><\/h2>\n

The most severe vulnerability in this release is CVE-2025-11458, a heap buffer overflow<\/a> in Chrome\u2019s Sync component that has been assigned a High severity rating.\u00a0<\/p>\n

Discovered by security researcher Raven at KunLun lab on September 5, 2025, this flaw earned a $5,000 bounty reward from Google\u2019s <\/a>Vulnerability Reward Program<\/a>.\u00a0<\/p>\n

Heap buffer overflows occur when a program writes data beyond the allocated memory buffer boundaries, potentially allowing attackers to corrupt adjacent memory regions and execute arbitrary code.<\/p>\n

The second critical vulnerability, CVE-2025-11460, represents a Use-After-Free<\/a> condition in Chrome\u2019s Storage component.\u00a0<\/p>\n

Reported by researcher Sombra on September 23, 2025, this High-severity flaw occurs when the browser attempts to access memory that has already been freed, creating opportunities for attackers to manipulate memory allocation and achieve code execution.\u00a0<\/p>\n

Use-after-free vulnerabilities are particularly dangerous as they can lead to complete system compromise when successfully exploited.<\/p>\n

Additionally, CVE-2025-11211 addresses an\u00a0out-of-bounds read<\/a>\u00a0vulnerability in WebCodecs, reported by Jakob Ko\u0161ir on August 29, 2025.<\/span>\u00a0<\/p>\n

This Medium-severity flaw, which earned a $3,000 reward, allows attackers to read memory outside allocated boundaries, potentially exposing sensitive information or facilitating further exploitation chains.<\/p>\n

Mitigations<\/strong><\/h2>\n

Google\u2019s security team employed<\/a> multiple advanced detection methodologies to identify these vulnerabilities, including AddressSanitizer, MemorySanitizer, UndefinedBehaviorSanitizer, Control Flow Integrity, libFuzzer, and AFL fuzzing techniques.\u00a0<\/p>\n

These automated security testing tools continuously analyze Chrome\u2019s codebase for memory corruption issues, race conditions, and other security-critical bugs before they reach production environments.<\/p>\n

The Chrome development team has implemented comprehensive mitigations within the browser\u2019s architecture, including sandboxing mechanisms that isolate rendering processes and limit the potential impact of successful exploits.\u00a0<\/p>\n

However, users must install the security update promptly, as Google restricts access to detailed vulnerability information until the majority of users have updated their browsers to prevent widespread exploitation of these critical flaws.<\/p>\n
